I have them on my car currently..... They last forever, i've had mine 2 years and put them through many auto crosses and a track day and about 9,000 other miles. In terms of tread depth they still look new...
In terms of performance they are garbage. 255whp with 4.10s and car weight of 3485 pounds with me in it i can roast the back tires shifting into 2nd gear.
Faster than a speeding...............
